DETAILED DESCRIPTION

[Detailed Description of the Invention]
[0001]

[Field of the Invention] Especially this invention relates to the system to offer information and
the information offer approach for the mobile users who offer the trend information which
learned not only each user s taste but a user ensemble s taste to the user who carries a
Personal Digital Assistant about the system to offer information and the information offer
approach for users, learned further, and was acquired in consideration of each user's current
time, the current position, and taste.
[0002]

[Description of the Prior Art] Previously, the applicant for this patent used the broadcast for
communications services by Japanese Patent Application No. No. 312487 [ 11 to ], and indicated
per [ which receives the advertisement in consideration of the positional information of current
time and a user, and a user s taste information with a personal digital assistant ] system.
Moreover, the system which acquires an individual taste automatically is indicated from the
individual behavior pattern by Japanese Patent Application No. No. 290379 [ 1 1 to ]. In case
service using this system is enjoyed, a user carries the personal digital assistant which offered
the device which carries out GPS reference-by-location profit. As for the personal digital
assistant, it is possible for a user to recognize the store which goes frequently, and the point,
and it can extract a user's taste using the store and attribute information on the point.
[0003] Moreover, the coordination filtering technique is known as structure for collecting
individual information, performing grouping and performing the common proposal for every group.
For example, using the coordination filtering technique, from the past hysteresis, a customer s
taste and needs are learned and the technique (http://www.netperceptions.com/) of performing
One-to-One marketing by which the PASONA rise was carried out more is offered.
[0004]

[Problem(s) to be Solved by the Invention] The system (Japanese Patent Application No. 11-
312487, Japanese Patent Application No. 11-290379) mentioned above offers the information
reflecting the taste of the user who learned in the area which the user had carried out. If it puts
in another way, these systems can offer only the information only in consideration of the taste
information learned with user's individual's usual behavior pattern. For this reason, in the area
which the user visited for the first time, even if it offers the reflected information when
information reflecting that user's taste information cannot be offered, the case of being
meaningless may arise.

[0005] For example, in order that a certain user may go in Tokyo to an Italian restaurant
frequently, the case where what "the Italian cuisine is liked for" as the user s taste information
is learned, and the user travels Hakone is considered. In this case, a system provides that user
with the information on the Italian restaurant in Hakone. However, when the user also has taste
of liking the local culinary specialties of the land at a tourist resort, a user thinks that he wants
the information on local culinary specialties. However, with the technique expressed above, since
the store of the local culinary specialties which a user has not performed is not learned, a user
is not provided with the information.

and PDA (Personal Digital Assistant), carry. Personal Digital Assistant 120 consists of the
location management tool 121, a communication management means 122. and an information
presentation means 123.

[0017] The location management tool 121 acquires the location of Personal Digital Assistant 120.
and manages positional information. The location management tool 121 acquires positional
information using GPS (Global Positioning System) etc. The communication management means
122 transmits the positional information transmitted from the location management tool 121,
measurement time of day, and user ID to a pin center.large 100. For example, the data to
transmit have DS like drawing 2 . In addition, of course, it is not necessary performing time-of-
day measurement in the pin center,large. then to transmit measurement time of day.
[0018] The information presentation means 123 shows a user the data transmitted from the pin
centerjarge 100. For example, the data of DS like drawing 3 are transmitted. For example, in
drawing 3 , if provided information 304 is HTML document data, the information presentation
means 123 is a WWW browser. Moreover, for example, in drawing 3 , if provided information 304 is
voice data, the information presentation means 123 is ai voice regenerative apparatus.
[0019] A pin center.large 100 includes means of communications 101, the user situation
matching means 102, the User Information material extract means 103. the taste study means
104, the user taste information DB105. the spot information DB106. the ensemble taste study
means 107. the ensemble taste information DB108, the information input means 109. and the
means 1 10 for information providers.

[0020] The communication management means 101 transmits the information ( drawing 2 )
received from a users Personal Digital Assistant 120 to the user situation matching means 102.
Moreover, spot information ( drawing 3 ) is transmitted to Personal Digital Assistant 120. The
spot information furthermore transmitted from the terminal 130 for information providers is
stored in the spot information DB106. and ensemble taste information is transmitted to the
terminal 1 30 for information providers.

[0021] The user situation matching means 102 acquires the spot information suitable for a user's
situation (time amount, a location, taste) from the spot information DB106 based on the data
(the user ID 200 of drawing 2 , positional information 201, measurement time of day 202)
transmitted from the information personal digital assistant 120; The taste information taken into
consideration in the case of matching is the information which unified two, the taste information
of this user that extracted from the user taste information DB105, and a user ensemble's taste
information that this user that extracted from the ensemble taste information DB belongs.
[0022] From the communication management means 101. the User Information material extract
means 103 transmits the data ( drawing 2 ) of Personal Digital Assistant 120 to reception, and
transmits those data to the taste study means 104.

[0023] From the data transmitted from the User Information material extract means 103, the
taste study means 104 extracts a users behavior pattern, and learns a user's taste. For example,
the taste study means 104 specifies the spot at which the user stayed from the positional
information 201 and the measurement time of day 202 of drawing 2 . The spot information DB106
is retrieved and the information on the spot ( drawing 3 ) is searched for. A user s taste
information is extracted based on the attribute information 302 showing the attribute of the spot
information on a retrieval result. The taste information of the user who corresponds by user ID is
accessed, and the taste information of the user within the user taste information DB105 is
updated.

[0024] The data with which a users taste information DB105 made the group taste information
of user ID 200 and its user are stored. For example, a user s taste information is expressed by
the keyword list showing a user's taste. Moreover, weight is given to the keyword which
expresses a user's taste, for example, and taste information is expressed by the keyword vector
(the list of keywords, and group of weight). Furthermore, the keyword vector which expresses a
user's taste, for example is managed in the group of a hour entry and the information on a
location. For example, both a user's behavior patterns computed with the taste study means 104
are also stored.

[0026] The ensemble taste study means 107 acquires a user ensemble s taste information from
the user taste information DB105. and learns a collective taste. For example, the grouping of the
user to whom profile information, taste, and profile information are similar is performed, and an
ensemble is made. A collective taste is extracted from the behavior pattern of the user who
belongs, or each user s taste information for every ensemble. Collective taste information is
stored in the ensemble taste information DB108,

[0027] A user ensemble's taste information is stored in the ensemble taste information DB108.
For example, the taste information acquired from the taste information which unified the list of
the information showing the taste of the ensembles, such as a keyword list, and the user ID 200
belonging to an ensemble and the taste of the user belonging to the ensemble, or a behavior
pattern is stored for every user ensemble.

[0028] The information creation means 110 for information providers accesses the ensemble
taste information DB108. extracts required ensemble taste information for every information
provider, and it requires it of the communication management means 101 so that it may transmit
to each information provider.

[0029] The information input means 109 stores in the spot information DB106 the contents of
the spot information transmitted from the terminal 1 30 for information providers.
[0030] The terminal 130 for information providers includes the communication management
means 131, the spot information authoring means 132. the spot information DB133, and the
ensemble taste information DB134.

[0031] The spot information authoring means 132 is a means used in case an information
provider creates the contents of spot information, and the contents after creation are stored in
the spot information DB1 33.

[0032] Data with DS as shows the spot information DB133 to drawing 3 are stored.
[0033] The communication management means 131 manages the communication link with a pin
center.large l6o. The spot information which the information provider created is transmitted to a
pin center.large 100, and the ensemble taste information which the pin center.large 100 learned
and acquired is received. The received ensemble taste information is stored in the ensemble
taste information DB1 34.

[0034] The taste information of the user ensemble who mainly receives the contents to which
the information provider created the ensemble taste information DB134 is stored. For example,
an information provider is an advertiser, and when the created spot information is an
advertisement, the customer information on the goods which should be advertised is stored.
[0035] The radio circuit 150 connects between Personal Digital Assistant 120. a pin center.large
100, and the terminal 130 for information providers. For example, it is possible to use a cellular
phone and the Internet.

[0036] Next, actuation of this invention is explained. First, actuation of Personal Digital Assistant
120 is explained with reference to drawing 4 and 5. In Personal Digital Assistant 120. if it
becomes the timing which transmits positional information ( drawing 4 step B1), the location
management tool 121 will extract positional information, and will record measurement time of
day. The communication management means 1 22 transmits ID of the user who is carrying
Personal Digital Assistant 120 registered, and the positional information and measurement time
of day which were received from the location management tool 121 to a pin center.large 100
( drawing 4 step B-2).

[0037] The communication management means' 122 reception of the spot information ( drawing
3 ) transmitted from the pin center.large 100 presents the spot information received to a user's
Personal Digital Assistant ( drawing 5 step B1 1). ( drawing 5 step BIO) For example, in drawing
3 , if provided information 304 is HTML document data, the information presentation means 123
is a WWW browser. Moreover, if provided information 304 Is voice data, for example in drawing 3 .
the information presentation means 1 23 is a regenerative apparatus.
[0038] Next, actuation of a pin center.large 100 is explained with reference to drawing 6 -
drawing 8 .

[0039] In the pin center.large 100, means of communications 101 receives the data ( drawing 2 )
situation from a user's information personal digital assistant 120 ( dra wing 6

step A1). Means of communications 101 transmits the received data to the User Information
material extract means 103 and the user situation matching means 102 ( drawing 6 step A2). For
example, the User Information material extract means 103 is equipped with the buffer which
saves the data ( drawing 3 ) of the received user situation.

[0040] With the user situation matching means 102, it investigates whether it is spot information
presentation timing to the user who transmitted the data ( drawing 2 ) of a user situation
( drawing 6 step A4). For example, the information on each user's spot information presentation
timing is memorized within the user situation matching means 102. Moreover, for example, the
information on each user's spot information presentation timing is stored in the user taste
information DB, is retrieved by user ID, and makes it possible to extract.

[0041] When it is spot information timing ( d rawin g 4 step A4), the spot information on the spot
information DB106 ( drawing 3 ) is retrieved [ the measurement time of day 202 ] for the value of
time amount, and a user's positional information 201 a condition [ the value of a location, and the
value of taste ]. The value of taste is data which unified the taste information of this user that
accessed the user taste information DB and searched for it by user ID 200, and two taste
information of a user ensemble extracted from the ensemble taste information DB108 that this
user belonged in that case.

[0042] For example, filtering according the spot information within the spot information DB to
time amount, filtering by the location, and filtering by taste are performed, and spot information
is sorted from the sum total of the score computed by three filtering. And this user will be
provided with the spot information on the rank of a high order.

[0043] For example, filtering by time amount is extracted only to the spot information only on the
restaurant which does business at the present time of day, and the spot suitable for sightseeing.
[0044] For example, in filtering by the location, although it is near from this user location, spot
information is calculated to make it rank it as a high order.

[0045] For example, the taste information of the user within the user taste information DB105
and the taste information of the ensemble within the ensemble taste information DB are
expressed by the keyword vector which shows taste, and the case where the attribute
information 302 on spot information is also expressed by coincidence by the keyword vector
again is considered. The similarity of the keyword vector showing this user s taste and the
keyword vector of spot information is calculated. The similarity of the keyword vector which
similarly expresses the taste of the user ensemble to whom this user belongs, and the keyword
vector of spot information is calculated. Two computed similarity is unified, the list of spot
information is sorted in order of what has a high score, and it considers as the spot information
which shows a user only the thing of a high order.

[0046] For example, in case the similarity of the comparison result of a user's taste information
and spot information and the similarity of the comparison result of collective taste information
and spot information are unified, it is possible to decide whenever [ two effect / of a count
result ] beforehand, and to place it. What is necessary is for it to be large in whenever [ effect /
of the similarity from a user's taste information and spot information ] to set weight to a user s
taste, and just to enlarge whenever [ effect / of the similarity from collective taste information
and spot information ] to set weight to a collective taste.

[0047] For example, when a user visits a certain area for the first time, there is no information
from taste study of the user about the area. Therefore, on the whole, the similarity of the
comparison result of the taste information on a user independent and spot information becomes
low. In that case, whenever [ effect / of the similarity computed from collective taste
information ] is enlarged. When it is in the area which it visits for the first time by that cause, it
becomes possible to offer the information for which are suitable based on the taste of the
ensemble to whom this user belongs. When it is below the constant value that has the similarity
average computed from the taste information on a user independent as an example of the
approach, a certain fixed price increase ****** is considered in whenever [ effect / of the
similarity computed from collective taste information ]. ( Drawing 6 step A5)
[0048] The spot information after filtering is transmitted to the user situation matching means

transmitted to this users Personal Digital Assistant 120 ( drawing 6 step A6).

[0049] Actuation of the taste study in a pin center.large 100 is explained with reference to

drawing 7 .

[0050] If the taste study means 104 becomes taste study timing, it will acquire the data
( drawing 2 ) of a user situation saved for a users information material extract means 103. The
taste study means 1 04 extracts only the data of the same user s situation, and detects the
positional information of the spot which can be recognized as stay with a users behavior pattern
(drawing 7 step A1 1X

[0051] For example, with the taste study means 104, when memorizing the value of the stay
qualification time amount X "stay can be presumed if it is made a certain point (GPS LAT LONG
+ radius r) more than X part" and having passed over X, it is considered that I stayed at the
spot Moreover, suppose that it also has the value of a radius r within the taste study means
104.

[0052] The taste study means 104 retrieves the spot information ( drawing 3 ) applicable to the
spot recognized as my having stayed for the spot information DB ( drawing 7 step A12).
[0053] The taste study means 104 retrieves this user's taste information for a user's taste
information DB105 ( drawing 7 step A13).

[0054] the information on the attribute information 302 on spot information, and relevant to taste
in the taste study means 104 — extracting — a user's taste information — an addition — or it
creates ( drawing 7 step A 14).

[0055] For example, when it is the keyword list for which expresses a user's taste by the
keyword list, and the attribute information 302 expresses the provided information 304 of spot
information, the keyword is added to the keyword list showing a user's taste.
[0056] Moreover, when the keyword which expresses a user s taste, for example is managed with
time amount and the information on a location, the keyword list of positional information 201 . the
measurement time of day 202, and taste is made into a group, and the data is updated.
[0057] The data with which a user's taste information DB105 made the group taste information
of user ID 200 and its user are stored. For example, a user s taste information is expressed by
the keyword list showing a user's taste. Moreover, weight is given to the keyword which
expresses a user's taste, for example, and taste information is expressed by the keyword vector
(the list of keywords, and group of weight). Furthermore, the keyword vector which expresses a
user's taste, for example is managed in the group of a hour entry and the information on a
location.

[0058] The taste study means 104 was updated or stores a users newly created taste
information in the user taste information DB105 ( d rawin g 7 step A15).

[0059] Next, actuation of the ensemble taste study in a pin center.large 100 is described with
reference to drawing 8 .

[0060] If the ensemble taste study means 107 becomes ensemble taste study timing ( drawing 8
step A20), it loads a user's taste information from the user taste information DB105 ( drawing 8
stepA21).

[0061] For example, the timing of ensemble taste study is recorded with the ensemble taste
study means 107. The ensemble taste study means 107 learns taste information for every user
ensemble ( drawing 8 step A22).

[0062] For example, from the user taste information DB105. the ensemble taste study ensemble
107 does grouping of a user's ensemble from a user's taste information information, unifies the
taste information of the user in an ensemble for every user ensemble of the, and makes the
result a study result

[0063] For example, in the case of time amount and the taste information in consideration of a
location, a user ensemble's taste information also unifies [ the taste information within the user
taste information DB ] the taste information of the user in each ensemble in consideration of
time amount and a location.

[0064] For example, from the user taste information DB105, when the behavior pattern is stored
for every user within the user taste information DB, after carrying out grouping of a user's,
ftnsemble from a user's taste information information, the ensemble taste study ensemble 107

extracts a collective taste from the user ensemble's behavior pattern, and makes the result a
study result The ensemble taste study means 107 makes the data of a study result reflect to

the ensemble taste study DB108 ( drawing 8 step A23).

[0065] A user ensemble s taste information which the ensemble taste study means 107 is a
certain timing, and is made into an information provider's object is retrieved ( drawing 8 step
A24).

[0066] For example, the ensemble taste study means 107 has memorized the data of the
candidate user ensemble for every information provider, and the timing of information offer.
[0067] The ensemble taste study means 107 transmits a retrieval result to means of
communications 101. and means of communications 101 transmits the target user ensemble's
taste information to each information provider ( drawing 8 step A25).

[0068] Actuation of the terminal 130 for information providers is explained using drawing 9 and
drawing 10 .

[0069] With reference to drawing 9 , actuation of spot information authoring of the terminal 130

for information providers is explained.

[0070] An information provider does authoring of the spot information ( drawing 3 ) using the.
spot information authoring means 132 ( drawing 9 step CI).

[0071] the spot information which the spot information authoring means 132 was created, or was
updated — the spot information 133 ~ storing ~ or it updates. And new spot information is
transmitted to a pin center.large 100 through the communication management means 131
( drawing 9 step C2).

[0072] Next, with reference to drawing 10, the actuation which receives the ensemble taste
information on the terminal 1 30 for information providers is explained.

[0073] The target user [ means / 131 / communication management / information provider / a
pin center.large 100 to ] ensemble s ensemble taste information is received ( drawing 10 step
CIO).

[0074] The communication management means 131 stores the received data in the ensemble
taste information DB134 ( drawing 1 0 step C11). An information provider develops future goods
with reference to the data stored for the ensemble taste information DB134.
[0075]

[Effect of the Invention] Since an individual user s taste not only learns, but according to this
invention it can learn a user ensemble s taste and trend information can be offered in
consideration of each user s current time, the current position, and taste to the user who carries
a Personal Digital Assistant based on a collective taste as the above was explained, it becomes
possible to offer the effective information for a user. Moreover, since an information provider is
provided with the target user ensemble s ensemble taste information, it is utilizable for
marketing. And when the information with which a user is provided is advertising information, it
enables the advertiser who is an information provider for customer information to come to hand.
